GRAIN- DRILL.

SPECIFICATION forming part of Letters Patent N 0. 637,767, dated November 28, 1899.

Application filed September 25, 1899. Serial No. 731,554. (No'modelJ To all 'whom it may concern.-

Be it known that we, GAYLARD W. DEN YES and OWEN SCHUTT, citizens of the United States, residing at Dowagiac, in the county of Cass and State of Michigan, have invented certain new and useful Improvements in Grain- Drills; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in grain-drills, and more particularly to that class commonly known as shoe-drills; and its object is to provide improved means for yieldingly forcing the shoes into the soil when in action and for lifting the same clear of the ground when out of action and to provide the device with certain new and useful features, hereinafter more fully described, and particularly pointed out in the claims.

Our invention consists, essentially, in providing the machine with an adjustable rockshaft having an arm for each shoe and flexible mechanism connecting each arm to the respective shoe, whereby the shoe is yieldingly pressed into the soil or lifted free from the same, according as the rock-shaft is adjusted, and in certain other details of construction, as will more fully appear by reference to the accompanying drawings, in which-- Figure 1 is a plan view of a device embodying our invention, and Fig. 2 a side elevation of the same.

A represents a portion of the frame of the machine; B is one of the drill-shoes; C C are the drag-bars, extending forward and upward from the drill-shoe and pivotally connected to the frame; D is the grain chute or tube, attached to the drill-shoe and extending upward therefrom, all as heretofore constructed.

A link F embraces the tube D and is pivoted at its rear end to a boss projecting from the rear of said tube and having its axis transverse to the axis of the tube. This link rests upon lugs E, projecting laterally from the tube,thislink being in substantially a horizontal position when in contact with the lugs and free to rise at the forward end, to which end are pivoted the lower ends of flexible rods G, preferably of spring-steel, which rods extend forward from the link, and thence are curved upward and backward, embracing the tube D, and thence extending vertically upward, terminating at each side of the vertically-movable end of the rocker-arm J, being pivotally attached thereto by means of a clamp I, hinged to the said arm and depending therefrom. These rods may be directly pivoted to the arm J, the same as to the link F; but we prefer to provide the clamp for the purpose of vertically and separately adjusting the rods G to adjust the relative tension of the rods. The arm J is attached to a rock-shaft K, suitably journaled and provided with an adjusting-lever L, having a holding-latch M, adapted to engage the various notches shown in the section N. Projecting from the tube D and adapted to engage the rods G are lugs D, and a clamp 11 is provided to prevent the rods G from spreading. It will be understood that the shaft K extends across the machine from side to side and is provided with a series of rocker-arms J for each of the series of drill-shoes B and that the usual means of supplying grain to the tube D and of supporting the frame is provided. When the lever L is moved forward, the arms are lowered. This moves the rods, and, being flexible, they yieldingly press the shoes B into the soil more or less according to such adjustment. When the lever L is moved back a suitable distance, the rods G are raised accordingly, and each link F rises clear of the lugs E. The shoes B are thus left to run freely upon the ground and enter the same by gravity alone. So also if anyone or more of the shoes should pass over any considerable depression the link would rise free of the lugs and permit the shoe to drop into .the said depression. By adjusting the lever backward sufficiently the rods G will engage the lugs D, and thus carry upward the tubes and parts thereto attached, raising the shoes clear of the ground. The lugs D slide on the rods G to adapt the parts to the changed position. \Ve thus by the described device provide for an adjustable spring-pressure upon the shoes or allow the shoes to run freely and enter the soil by gravity alone or drop into any unusual depression or lift the shoes entirely clear of the ground, as occasion requires, by merely adjusting a single lever 7 and adjust the springs separately for relative what we claim shoe to engage the lower side of'the link, a

to the shoe, and a vertically-adjustable sup-' "portattached to the upper end IO vertically-movable shoe, a flexible and bent shoe, and a vertically-adj ustable arm pivotvertically-nwvable shoe, a linkpivotally conmovable end of the link, an adjustable arm tension. 7

'Having thus fully described our invention,

I and desire to' secure by Letters Patent, isp 1. Ina grain-drill, a vertically:movable shoe, a flexible rod connected atits lower end of said rod, substantially as described. 2. In a grain-drill, the combination of a rod pivotally connected at its lower end to the ally connected to the upper end of said rod,

substantially as described. V

3. In a grain-drill, the combination of a.

verticallym0vable shoe, a yielding'connecting-rod pivotally connected to the shoe at the" lower end, an adjustable rock-shaft, and an arm on the. shaft pivotally connected to the upper end of said rod,-substantially as deg scribed. j r

4. In a grain-drill, the combination of a nectedv atone end to the shoe, lugs on the flexible and bent rod pivotally connected at its lowerend to the link,.aud a vertically adjustable support connected to the upper end of saidrod, substantially as described.

5. The combination of a vertically-movable shoe, a tube extending upward from the shoe, 3. link pivoted at one end to'the tube and vertically movable at the other end, a'yielding connecting rod pivotally' connected to the pivotally connected to the upper end of the rod, and a lug on the tube to engage the rod, substantially as described.

6. The combination of a vertically-movable shoe, an upwardlyprojecting tubev on the shoe, lugs on the upper end of the tube, flexible rods pivotally connected to the shoe, and extending forward, upward, and rearward, and embracing the tube, and thence extended upward, a rock-shaft having a lever, latch, and sector, and an arm on the rock-shaft pivotally connected to said rods, substantially as described. 4

7. The combination of a shoe, a tube extending upward from the shoe, a link pivotallyconnected at one endto theqtnbe', and vertically movable at the other end, lugs engaging the lower side of the link, flexible rods pivotally connected to the movable end of the link, and extending forward therefrom and thence upward and rearward, and thence again upward, said rods also being attached at their upper ends to a vertically-adj ustable support, and lugs on the upper end of the tubeto engage the rods, substantially as described. I

' 8. Ina grain-drill, the combination of a vertically-movableshoe, flexible and bent rods pivotally connected tothe shoeat their lower ends, and extending upward therefrom, a vertically-adjustable rocker-arm,-and a clamp hinged to the rocker-arm and adj ustably engaging the rods, substantially asdescribed.

9. The combination of a vertically-movable shoe, a tube extending upward therefrom, a

link pivoted. to the tube at one end, rods pivoted to the other end of the link and extending upward and rearward therefrom, and embracing. the upper end of the tube and thence extended vertically,"lugs .on the tube to engage the rods, a clamp on the rods to prevent spreadingof the rods, a clamp near the upper ends of the rods and adjustablethereon, and an adjustable rocker-arm hinged to the clamp, substantially as described. v

. 10.- The combination of a vertically-movable shoe, a tube extending upward from the shoe, a link embracing the tube and pivoted at one end to the tube, lugs engaging the under side of the link, flexible rods pivoted to the other end-of the'link and extending for.-

- ward, upward, and rearward therefrom, and

embracing the tube, and thence extending u pward, lugs on the tube to engage the rods, a

rock-shafthaving a lever, latch, and sector, an arm on the shaft, and a clamp hinged to the arm and adjustably engaging the upper ends of the said rods, substantially'as described.

In testimony-whereof We aflix our signatures in preseneeof two witnesses.
